Starting from 5e7612eb4, OpenOCD identifies itself as 0.12. This causes Microwatt's flash-arty script to fail. Because neither the cfg nor the proxy bitstream are affected, we can keep treating everything as indistinguishable from 0.11. This patch simply tests for "0.12" as an alias; it would probably be better to replace this confusing terminology with something like "single-tap/multi-tap".

The Xilinx SPI flashing proxies come from here:

https://github.com/quartiq/bscan_spi_bitstreams/blob/single-tap/bscan_spi_xc7a100t.bit?raw=true
These are the "old" single tap versions that are supported by the openocd
release packaged in distros (0.10). If you use the wrong versions you see this:
$ ./openocd/flash-arty microwatt_0.bit

If you find yourself with a later openocd version that contians 867bdb2e9248
("jtagspi: new protocol that includes transfer length"), such as v0.11 as
packaged by Debian Bullseye, you should use the bitstream from the master
branch:
https://github.com/quartiq/bscan_spi_bitstreams/blob/master/bscan_spi_xc7a35t.bit?raw=true
https://github.com/quartiq/bscan_spi_bitstreams/blob/master/bscan_spi_xc7a100t.bit?raw=true
These are in the microwatt repository as bscan_spi_xc7a*t_openocd_v0.11.bit.
